Daily Objectives #17  (October 24, 2006)                                                                        Dr. Sanders

By the end of today’s class, you should be able to do the following:


*  Explain why and how rocks can undergo metamorphism, and in what plate tectonic setting it might take place.

*  List and describe two major textural changes that occur when rocks undergo metamorphism.

*  Examine hand samples and describe the properties of common minerals that occur in metamorphic rocks.  (Examples used in class: numbers 4, 5, 7, 9, 16, 23, 25, 30, 31, 39).

*  Examine hand samples of metamorphic rocks, describe their features, and use a key (textbook p. 73) to identify their names.  (Examples used in class: 101, 105, 115, 116, 131, 140, 147).

*  List the names of the metamorphic rocks that result from metamorphism of sandstone, granite, limestone, and shale, and tell how each of these protoliths is different from and similar to the metamorphic rock.

Homework #3 will be due next Thursday, November 2.  (The assignment will be posted later this week.)  It will require you to understand and use measurements of latitude and longitude, and to know what east and west mean in that context.  If you are not completely confident of your ability to use these concepts, please try out some of the many helpful tutorials on the web.  (Try googling "latitude longitude tutorial" to find some of them.)
